USA Today estimates nearly 11 million people are in this country illegally — a drastic jump from the 1.9 million illegal immigrants recorded in 1988 — effectively guaranteeing illegal immigration will remain a hot-button issue during the next presidential term.

On the other hand, President Barack Obama has urged Congress to pass the DREAM Act, which would help young illegal immigrants gain citizenship. He has also offered illegal immigrants brought here as children a two-year work permit.

Meanwhile, back in Arizona, voters must decide whether to continue promoting, or at least tolerating, Arpaio's vigilante practices.

The popular sheriff, who in the past 20 years has never been reelected by less than 12 points, is facing a slew of legal problems, including wrongful death lawsuits and civil rights violations allegations, according to Mother Jones.
